Geez that's a bummer. My wife and I are going this summer and I've been researching all of the different scams. Definitely going to get a belt wallet for me and her, it sounds like pick pocketing is the most common issue.
I did this before I relocated there for a few years. It will raise your blood pressure and you'll be trying so hard to protect yourself from one scam that you'll get hit by another, and by the time you've done researching you'll have so little trust that you might see everything as a potential robbery.
Enjoy your time there, it's a beautiful city! Just make sure to minimise your risk by limiting what you carry around with you and never take your eyes off it. That way if you do get unlucky, you can still recover from it.
